Generally, every section has its footing. Isolated footing comprises a foundation directly at the base of the segment. Figure: Isolated shallow foundation image They are generally used for ordinary buildings (Typically up to five stories). They are typically utilized for shallow establishments to convey and spread concentrated burdens caused, for instance, by pillars or columns. This is the most widely recognized and most straightforward shallow foundation type, as this is the most economical type. The followings are the types of shallow foundations. Several types of shallow foundations are discussed below. Shallow FoundationsĪs the shallow foundation depth is low and it is economical, it is the most popular type of foundation for lightweight structures. To know other factors that affect the range of foundation read: Factors Considered for Selection of Foundation. As economic feasibility is one of the main factors in the type selection, it is also discussed briefly with each type. The main aspects of different types of foundation, along with their images, are given below. If the width is smaller than the depth of the foundation it is called as “Deep Foundation.” However, deep foundation and shallow foundation can be classified as shown in the following chart. Generally, if the width of the foundation is greater than the depth, it is labeled as the “Shallow Foundation”. The terms Shallow and Deep Foundation refer to the depth of the soil at which it is placed. In general, all foundations are divided into two categories, - shallow and deep foundations. Depending on the soil profile, size, and load of the structure, engineers chose different kinds of foundation.
Prevent the lateral movement of the structure.Īs we know that there are different types of soil, and the bearing capacity of the soil is different for each type of soil.Distribute the weight of the structure over a large area of soil.Why a Foundation is Providedįoundation should fulfill the following objectives: The solid ground on which it rests is known as foundation bed. Foundation is the part of a structure on which the building stands. It is defined as that part of the structure that transfers the load from the structure constructed on it as well as its weight over a large area of soil in such a way that the amount does not exceed the ultimate bearing capacity of the soil and the settlement of the whole structure remains within a tolerable limit. Foundation is one of the essential parts of the structure.
